with trimethylsilyl thioethers in the presence of rhodium(II) catalysts to generate α-allyl-α-thio silyl esters. The transformation involves a tandem process involving formal rhodium-catalyzed insertion of the carbene group into the S–Si bond to generate a silyl ketene acetal, followed by a spontaneous Ireland–Claisen rearrangement. The silyl ester products were isolated as the corresponding carboxylic

A series of milnacipran analogs were synthesized and studied as monoamine transporter inhibitors, and several potent compounds with moderate lipophilicity were identified from the 1S, 2R-isomers. Thus, 15l exhibited IC50 values of 1.7 nM at NET and 25 nM at SERT, which were, respectively, 20- and 13-fold more potent than 1S, 2R-milnacipran 1-II. (C) 2008 Elsevier Ltd. All rights reserved.
